    Tried to create and primary key

    My code is correct Table1 

      Create table (P_Id not the original primary key, LastName varchar ( 255) No NULL, FirstName Varkar (255), Address Worker (255), City Worker (255));   
      Table 2 :  
      create table order (O_Id integer no NULL primary key, OrderNo integer (10), integer foreign P_Id principal reference person (P_ID));   
     Error: -ORA-00907: missing right bracket  
     Do not know what the error is.   
     
     foreign key  keyword:  
      table Create an order (O_Id not the original primary key, not the order int (10), P_Id int reference persons (P_Id));   
     Btw: When you also use an inline definition, the column name list is not needed  P_Id integer reference people will suffice .  
     This will hamper the name of a system (such as  SYS_C0066866 ), then it is generally better to use a format where you can specify the name of the obstacle:    
     prefixing the order of the order (O_Id integer no NULL primary key, OrderNo integer (10), P_Id integer, foreign key (p_id fk_orders_person constraint) persons (P_Id) reference;

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
